[PATCH] net: sched: cls_u32: use bitwise & rather than logical && on n->flags

From: Colin King
Date: Fri Nov 03 2017 - 04:10:18 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Currently n->flags is being operated on by a logical && operator rather
than a bitwise & operator. This looks incorrect as these should be bit
flag operations. Fix this.

Detected by CoverityScan, CID#1460398 ("Logical vs. bitwise operator")
